It has grown from the simple communication medium of the god-awful earpieces everyone hates you for wearing into a widely-used wireless audio standard. Portable speakers, cars, and headphones are all latching onto it. But what about your 2.1 system? I know I've always wished I could easily push music to my own stereo setup without messy PC software or dongle attachments.
